Websocket test ok with browser but crashes with Gatling

[Sergi González]

Hi guys,

I'm currently developing a Play Framework application with websockets and I want to do some load test with Gatling.

When I test my application opening a webserver from Chrome Dev tools everything looks ok:

But when I try to do the same with Gatling I get "Invalid status code 0". I think there is no problem without Gatling ... I think the problem is with Play but I'm not sure... I have tested my Gatling test with http://www.websocket.org/echo.html and it works.

My Gatling test:

class BasicTest extends Simulation {

  val httpConf = http

    .baseURL("http://localhost:9000")

    .wsMaxReconnects(1)

    .header("Sec-WebSocket-Version", "13")

    .header("Sec-WebSocket-Extensions" , "permessage-deflate client_max_window_bits")

    .acceptLanguageHeader("en-US,en;q=0.5")

    .acceptEncodingHeader("gzip, deflate")

    .userAgentHeader("Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.73 Safari/537.36")

    .wsBaseURL("ws://localhost:9000")

  

  val scn = scenario("WebSocket")

    .exec(ws("Connect WS").open("/socket"))

    .pause(10)

    .exec(ws("Close WS").close)

  setUp(scn.inject(rampUsers(1) over 1.seconds)).protocols(httpConf)

}

I get a similar error using wscat

I'm new in websockets stuff... so, any idea about what's going on will be appreciated.

Regards,

Sergi

Same answer as on SOF: http://stackoverflow.com/questions/34061078/websocket-works-in-browser-but-hangs-from-other-clients

Sample plz

But what's sure is that Gatling doesn't support WebSocket Extensions atm.

Hi, 

The code is not public...

I'm testing now against https://github.com/JAVEO/clustered-chat#master which is pretty the same than my application and I get same results... "Invalid Status Code 0"

I don't know if is something about my machine (mac os) but i have created another ws server with wscat (wscat -l 8080 -p 13) and pointing to this, my Gatling test works.

Ok,

Now it works. Play by default works in port 9000 and I had this port binded with php-fpm.... But I still don't understand why Play not crashes when trying to bind the application to an already binded port. 

Thanks guys.
